As the bill sensor 31, it is possible to use various well-known devices such as a device that detects a magnetic field change due to approach of a bill and a device that detects presence or absence of blocking of an optical path by a bill. The bill sensor 31 is an example of the article detecting section.

The operation of the self-checkout apparatus 100 configured as explained above is explained.

If the self-checkout apparatus 100 is in an operating state, the CPU 21 waits for various instructions to be given to the CPU 21. If operation for instructing implementation of accounting concerning a commercial transaction is performed, for example, on the touch panel 10, the CPU 21 starts, in response to the operation, control processing according to the control program stored in the ROM 22. Note that content of processing explained below is an example. Various kinds of processing capable of obtaining the same result can be used as appropriate.

FIG. 4 is a flowchart of the control processing by the CPU 21.

In Act 1, the CPU 21 performs registration processing for registering a purchased commodity. Specifically, the CPU 21 waits for registration operation by the operator to be performed. The registration operation is, for example, an operation for holding the purchased commodity in front of the scanner window 11, an operation for bringing the handy scanner 12 close to a barcode displayed on the purchased commodity, or an operation for touching the touch panel 10 in order to designate the purchased commodity.

If the purchased commodity is held in front of the scanner window 11, the fixed scanner 24 recognizes, with image processing, the barcode displayed on the purchased commodity and sends information represented by the barcode to the CPU 21. If the handy scanner 12 is brought close to the barcode, the handy scanner 12 identifies the barcode and sends the information represented by the barcode to the CPU 21. If an operation for touching the touch panel 10 is performed in order to designate the purchased commodity, the touch panel 10 sends position information concerning a touch position to the CPU 21.

The CPU 21 determines, as a commodity code of the purchased commodity, a commodity code included in the information sent from the fixed scanner 24 or the handy scanner 12 or a commodity code associated with the touch position sent from the touch panel 10. The CPU 21 updates information in a commodity list area set in the RAM 23 in order to add the commodity identified by the commodity code to a list of purchased commodities.

If registration of all purchased commodities is finished and operation for instructing implementation of accounting processing is performed, for example, on the touch panel 10, the CPU 21 ends the registration processing and proceeds to Act 2.

In Act 2, the CPU 21 performs the accounting processing. Specifically, the CPU 21 calculates a settlement amount that should be settled for purchase of all the registered purchased commodities. The CPU 21 settles the calculated settlement amount using a settlement method designated by the operator out of a plurality of settlement methods. As the settlement method, it is possible to appropriately use various settlement methods for using cash, a credit card, a debit card, a prepaid card, electronic money, points, notes, and the like. The CPU 21 executes the control processing based on the control program in this way, whereby the computer including the CPU 21 as the principal portion functions as a settling section.

In Act 3, the CPU 21 checks whether change is paid as a result of the settlement processing. If determining Yes because change is paid, the CPU 21 proceeds to Act 4.

In Act 4, the CPU 21 determines payment amounts for respective denominations on the basis of a change amount calculated in the accounting processing. The CPU 21 instructs the coin paying and receiving unit 28 to discharge the payment amount of coins and instructs the bill paying and receiving unit 30 to discharge the payment amount of bills. In response to the instruction, the coin paying and receiving unit 28 and the bill paying and receiving unit 30 respectively drive the discharging unit 28 a and the discharging unit 30 a to discharge the coins and the bills as the change. The discharged coins and bills are held by the change tray 16 and the bill discharge port 19. In this way, if the coin paying and receiving unit 28 discharges the coins, the coin sensor 29 detects the coins. If the bill paying and receiving unit 30 discharges the bills, the bill sensor 31 detects the bills. The CPU 21 executes the control processing based on the control program in this way, whereby the computer including the CPU 21 as the principal portion functions as a discharge control section. A function of a discharge section is realized by cooperation of the discharging unit 28 a and the discharging unit 30 a and the CPU 21.

In Act 5, the CPU 21 checks whether the change discharged as explained above remains in the change tray 16 or the bill discharge port 19. If the coin sensor 29 or the bill sensor 31 detects the coins or the bills, the CPU 21 determines Yes and proceeds to Act 6.

In Act 6, the CPU 21 checks whether a prescribed time elapses after the change is discharged. If determining No because the prescribed time does not elapse yet, the CPU 21 returns to Act 5. It is assumed that the prescribed time is, for example, 60 seconds. However, the prescribed time may be optional. The prescribed time may be set by, for example, a designer of the self-checkout apparatus 100 or an administrator of the self-checkout apparatus 100.

In this way, in Act 5 and Act 6, the CPU 21 waits for the prescribed time to elapse in a state in which the change remains. If determining Yes in Act 6 because the prescribed time elapses, the CPU 21 proceeds to Act 7.

In Act 7, the CPU 21 checks whether the operator is opposed to the self-checkout apparatus 100. If the human sensor 27 is in a detecting state, the CPU 21 determines Yes and proceeds to Act 8.

In Act 8, the CPU 21 checks whether the change remains in the change tray 16 or the bill discharge port 19. If the coin sensor 29 or the bill sensor 31 detects coins or bills, the CPU 21 determines Yes and returns to Act 7.

In this way, in Act 7 and Act 8, the CPU 21 waits for the operator to leave the front of the self-checkout apparatus 100 or all the change to be removed.

If the human sensor 27 is in an un-detecting state, the CPU 21 determines No in Act 7 and proceeds to Act 9. In this way, if the operator leaves the front of the self-checkout apparatus 100 while leaving the change behind before the prescribed time elapses after the change is discharged or after the prescribed time elapses after the change is discharged, the CPU 21 proceeds to Act 9.

In Act 9, the CPU 21 instructs the printer 25 to print an untaken article slip. Specifically, the CPU 21 generates an image shown on the untaken article slip and gives the image to the printer 25. The printer 25 prints the image given from the CPU 21 on a receipt sheet with the receipt printer and discharges the receipt sheet from the receipt issue port 13.

FIG. 5 is a diagram showing an example of an untaken article slip 40.

The untaken article slip 40 includes a region 41, a region 42, and a region 43.

The region 41 shows a sentence for informing a situation of untaken change. In the example shown in FIG. 5, the region 41 shows a sentence for informing that only coins of the change are left untaken. When proceeding to Act 9, if the coin sensor 29 detects coins and the bill sensor 31 does not detect bills, the CPU 21 displays the sentence shown in FIG. 5 in the region 41. When proceeding to Act 9, if the coin sensor 29 does not detect coins and the bill sensor 31 detects bills, the CPU 21 displays, in the region 41, a sentence such as “Concerning the transaction described below, bills of change are left untaken”. When proceeding to Act 9, if the coin sensor 29 and the bill sensor 31 detect both of coins and bills, the CPU 21 displays, in the region 41, a sentence such as “Concerning the transaction described below, both of coins and bills of change are left untaken”.

The region 42 shows content of a transaction in which change is left untaken. What kind of information in information representing the content of the transaction is displayed in the region 42 is optional. The information displayed in the region 42 may be decided by, for example, the designer of the self-checkout apparatus 100 or the administrator of the self-checkout apparatus 100. In the example shown in FIG. 5, information for specifying the transaction in which change is left untaken such as a transaction number, a register number, a transaction date and time, and a list of purchased commodities is displayed in the region 42.

The region 43 shows a result of accounting. What kind of information in information representing the result of the accounting is displayed in the region 43 is optional. The information displayed in the region 43 may be decided by, for example, the designer of the self-checkout apparatus 100 or the administrator of the self-checkout apparatus 100. In the example shown in FIG. 5, a settlement amount, a consumption tax amount, a deposit amount, a change amount, and respective amounts of bills and coins of change are displayed in the region 43.

As explained above, the untaken article slip 40 is a voucher for making it possible to confirm afterwards that change, which is an example of an article, remains even if a prescribed time elapses after discharge. The CPU 21 executes the control processing based on the control program in this way, whereby the computer including the CPU 21 as the principal portion functions as a processing section.

In Act 10, the CPU 21 starts a warning operation. The warning operation is an operation for informing the store clerk that change is left untaken. The warning operation is, for example, flashing of the patrol lamp 20. The warning operation may be an output of warning sound or notification to other terminals. The warning operation may include a plurality of operations. In this way, the patrol lamp 20 is an example of an operating section that performs an alarming operation.

In Act 11, the CPU 21 checks whether change remains in the change tray 16 or the bill discharge port 19. If the coin sensor 29 or the bill sensor 31 detects coins or bills, the CPU 21 determines Yes and repeats Act 11. In this way, in Act 11, the CPU 21 waits for the untaken change to be removed.

For example, if the store clerk in charge of monitoring of the self-checkout apparatus 100 recognizes, for example, according to the warning operation that the change is left untaken, the store clerk removes the untaken change and stores the change together with the untaken article slip.

If the change is removed in this way, both of the coin sensor 29 and the bill sensor 31 do not detect coins and bills. Consequently, the CPU 21 determines No in act 11 and proceeds to Act 12.

In Act 12, the CPU 21 stops the warning operation started in Act 10. Consequently, the CPU 21 ends the control processing shown in FIG. 4.

Note that the CPU 21 omits other kinds of processing and ends the processing shown in FIG. 4 in any one of cases (1) to (3) described below. (1) The CPU 21 determines No in Act 3 because change is not paid as a result of the accounting processing in Act 2. (2) In the waiting state in Act 5 and Act 6, the CPU 21 determines No in Act 5 because both of the coin sensor 29 and the bill sensor 31 do not detect coins and bills before the prescribed time elapses. (3) In the waiting state in Act 7 and Act 8, the CPU 21 determines No in Act 8 because both of the coin sensor 29 and the bill sensor 31 do not detect coins and bills before the human sensor 27 changes to the un-detecting state.

As explained above, if the change is not removed from the change tray 16 or the bill discharge port 19 for the prescribed time, the self-checkout apparatus 100 is sues the untaken article slip. Therefore, the store clerk in charge of the monitoring of the self-checkout apparatus 100 can confirm afterwards, by storing the untaken change together with the untaken article slip, in which transaction the untaken change is left untaken. Therefore, the store clerk does not need to write a memorandum. It is possible to reduce labor of management of the untaken change.

The self-checkout apparatus 100 shows, on the untaken article slip, the content of the transaction in which the change is left untaken. Therefore, the store clerk can check, by, for example, collating content of a transaction described on a receipt carried by the shopper or content of a transaction claimed by a shopper, genuineness of the shopper who claims the untaken change later.

The self-checkout apparatus 100 performs the warning operation according to the issuance of the untaken article slip. Therefore, the store clerk can quickly remove the untaken change and the untaken article slip from the self-checkout apparatus 100 and manage both of the untaken change and the untaken article slip.

Even if the change is not removed from the change tray 16 or the bill discharge port 19 for the prescribed time, the self-checkout apparatus 100 does not issue the untaken article slip while the operator is detected by the human sensor 27. The self-checkout apparatus 100 issues the untaken article slip if the operator is not detected by the human sensor 27. Therefore, the untaken article slip is not issued by mistake if taking-out of change is delayed because, for example, a shopper is slow in taking out the change but the shopper does not seem to forget to take the change.

The self-checkout apparatus 100 creates the untaken article slip by printing the necessary information on the receipt sheet with the receipt printer included in the printer 25. Therefore, information shown on the untaken article slip is also printed on the journal sheet by the journal printer and stored. Therefore, for example, even if the untaken article slip is lost, it is possible to check afterwards concerning which transaction the change is left untaken.

Second Embodiment

A second embodiment is explained below with reference to the drawings. Note that, in the second embodiment, a self-checkout system including a self-checkout apparatus including a function of a settlement apparatus and an attendant apparatus including a function of a management apparatus is explained as an example.

If the self-checkout apparatus 210 is in an operating state, the CPU 21 waits for various instructions to be given to the CPU 21. If operation for instructing implementation of accounting concerning a commercial transaction is performed, for example, on the touch panel 10, the CPU 21 starts, in response to the operation, control processing according to the control program stored in the ROM 22. Note that content of processing explained below is an example. Various kinds of processing capable of obtaining the same result can be used as appropriate.

FIG. 7 is a flowchart of the control processing by the CPU 21. Note that acts same as the acts shown in FIG. 4 are denoted by the same reference signs. Detailed explanation of the acts is omitted.

In Act 1 to Act 8, the CPU 21 executes the processing in the same manner as in the first embodiment.

If the CPU 21 is in the waiting state in Act 7 and Act 8, the CPU 21 determines No in Act 7 and proceeds to Act 21 if the human sensor 27 changes to the un-detecting state. In this way, if the operator leaves the front of the self-checkout apparatus 210 while leaving the change behind before the prescribed time elapses after the change is discharged or after the prescribed time elapses after the change is discharged, the CPU 21 proceeds to Act 21.

In Act 21, the CPU 21 collects the remaining change. Specifically, if the coin sensor 29 detects coins, the CPU 21 drives the collecting unit 33 a to collect the coins remaining in the change tray 16. If the bill sensor 31 detects bills, the CPU 21 drives the discharging and collecting unit 34 a to collect the bills held by the bill discharge port 19.

In Act 22, the CPU 21 performs untaken article notification to the attendant apparatus 220. The untaken article notification is notification for causing the attendant apparatus 220 to issue an untaken article slip. Specifically, the CPU 21 controls the communication unit 35 to transmit notification information of a predetermined form for the untaken article notification to the network 300 while addressing the notification information to the attendant apparatus 220. The CPU 21 includes, in the notification information, information that should be shown on the untaken article slip or image data indicating an image representing the untaken article slip. Consequently, the CPU 21 ends the control processing shown in FIG. 7. The CPU 21 executes the control processing based on the control program in this way, whereby a function of a notifying section is realized by cooperation of the computer including the CPU 21 as the principal portion and the communication unit 35.

On the other hand, if the attendant apparatus 220 is in a normal operation state, the CPU 51 executes, according to the control program stored in the ROM 52, control processing for coping with notification from the self-checkout apparatus 210.

FIG. 8 is a flowchart of the control processing by the CPU 51.

In Act 31, the CPU 51 checks whether the untaken article notification is performed. If the untaken article notification is not performed, the CPU 51 determines No and proceeds to Act 32.

In Act 32, the CPU 51 checks whether another notification different from the untaken article notification is performed. If the relevant notification is not performed, the CPU 51 determines No and returns to Act 31.

In this way, in Act 31 and Act 32, the CPU 51 waits for the untaken article notification or another notification to be performed. If determining Yes in Act 32 because another notification different from the untaken article notification is received by the communication unit 56, the CPU 51 shifts to processing corresponding to the notification. Explanation of the processing performed at this point is omitted.

If the notification information is transmitted to the attendant apparatus 220 via the network 300, in the attendant apparatus 220, the communication unit 56 receives the notification information. If the untaken article notification is performed in this way, the CPU 51 determines Yes in Act 31 and proceeds to Act 33.

In Act 33, the CPU 51 instructs the printer 55 to print the untaken article slip. Specifically, if information that should be shown on the untaken article slip is included in the notification information for the untaken article notification, the CPU 51 generates an image representing these kinds of information and gives the image to the printer 55. If image data is included in the notification information for the untaken article notification, the CPU 51 gives an image indicated by the image data to the printer 55. The printer 55 prints the image given from the CPU 51 on a sheet and discharges the sheet. Consequently, the untaken article slip is issued in the attendant apparatus 220. The CPU 51 executes the control processing based on the control program in this way, whereby the computer including the CPU 51 as the principal portion functions as a processing section.

In Act 34, the CPU 51 starts a warning operation. The warning operation is an operation for informing the store clerk that the untaken article slip is issued. The warning operation is, for example, display of a message on the touch panel 54. Alternatively, the warning operation is an output of buzzer sound, chime sound, or the like by a not-shown sound emitting device. The warning operation may be any other operation or may include a plurality of operations.

In Act 35, the CPU 51 checks whether operation for checking issuance of the untaken article slip is performed. If the relevant operation is not performed, the CPU 51 determines No and repeats Act 35. In this way, in Act 35, the CPU 51 waits for the check operation to be performed.

For example, if a store clerk who monitors the self-checkout apparatus 210 using the attendant apparatus 220 recognizes that, for example, the untaken article slip is issued according to the warning operation, the store clerk stores the untaken article slip. Then, the store clerk performs check operation.

If the check operation is performed in this way, the CPU 51 determines Yes in Act 35 and proceeds to Act 36.

In Act 36, the CPU 51 stops the warning operation started in Act 34. Consequently the CPU 51 returns to the waiting state in Act 31 and Act 32.

In this way, with the self-checkout system 200, the store clerk who monitors the self-checkout apparatus 210 using the attendant apparatus 220 can recognize that change is left untaken in the attendant apparatus 220 without moving to the self-checkout apparatus 210. Consequently, the store clerk can easily and quickly recognize that the change is left untaken.

With the self-checkout system 200, the untaken change is automatically collected by the collecting unit 33 a and the discharging and collecting unit 34 a. Therefore, the store clerk does not need to move to the self-checkout apparatus 210 and can manage the untaken change only by storing the untaken article slip.

Various modified implementations described below of the embodiments are possible.

In the embodiments, by applying this application to a self-checkout apparatus including a function of managing, in time series, images obtained by picking up images of states of the operator with a camera, it is possible to easily specify, on the basis of information shown on the untaken article slip, an image in which a shopper who forgets to take change appears.

In the embodiments, as the processing for making it possible to check the untaken article afterwards, for example, processing described below may be applied instead of the printing of the untaken article slip.

-   (1) Information same as the information shown on the untaken article     slip is printed only on a journal sheet. -   (2) The information shown on the untaken article slip is stored in a     storage medium without being printed on any sheet. In this case, the     storage medium may be a storage medium provided in the self-checkout     apparatus or may be a storage medium provided in an external server     or the like. -   (3) In the case of a self-checkout apparatus adapted to a well-known     electronic receipt service, the untaken article may be notified to,     via an electronic receipt server, an information terminal registered     in advance owned by a shopper.

In the embodiments, this application can also be applied to a settlement apparatus of another form such as a settlement apparatus in a semi-self-type checkout system.

In the embodiments, the article is not limited to money serving as change and may be various cards such as a credit card and an electronic money card.

In the embodiments, transfer of the self-checkout apparatus 100 or 210 or the attendant apparatus 220 to a user is performed in a state in which the control program is stored in the ROM 22 or 52. However, the self-checkout apparatus 100 or 210 or the attendant apparatus 220 may be transferred to the user in a state in which the control program is not stored in the ROM 22 or 52 and the control program may be transferred to the user while being recorded in a removable recording medium or via a network. In this case, for example, according to operation by the user, the control program is written in the RAM 23 or 53 or a separately provided auxiliary storage unit such as a HDD (hard disk drive). As the removable recording medium, it is possible to use a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory, or the like.

In the first embodiment, the coin paying and receiving unit 33 may be provided instead of the coin paying and receiving unit 28. The bill paying and receiving unit 34 may be provided instead of the bill paying and receiving unit 30.

In the second embodiment, the coin paying and receiving unit 28 may be provided instead of the coin paying and receiving unit 33. The bill paying and receiving unit 30 may be provided instead of the bill paying and receiving unit 34. In this case, it is desirable that the self-checkout apparatus 210 notifies the attendant apparatus 220 of the removal of the change and, instead of Act 35, it is determined whether the notification is performed.

In the second embodiment, the processing for making it possible to check the untaken article afterwards can also be carried out in an apparatus other than the attendant apparatus 220 such as a registration apparatus in a semi-self-type checkout system, an information terminal set in a service counter, or an information terminal carried by the store clerk.
